Profit and premium models can be great if it's allocated to useful things. For example if it went as bonuses to the rank and file employees, or was as steam store credit, or went to a charity.
I get your cynicism it would just go to billionaire shareholders, but profit itself isnt the enemy, greed is.
greed isn't even the worst. greed is a necessity if you have any competition. sometimes it's hard to tell greed from operational efficicency.
rent seeking however... rent seeking should be taxed to hell and back.
